Duncan Taylor ruled out of Scotland's second Test with Japan through injury

The Saracens centre sustained the problem during Saturday's 26-13 win in the first Test and his fitness was being monitored by the Scottish medical team.

However, it was agreed that he wouldn't recover in time to be ready for this Saturday's match after failing to respond to treatment.

Scotland head coach Vern Cotter won't call up a replacement due to there being adequate cover in the position, with surprise inclusion Huw Jones now looking likely to earn his first cap.

Matt Scott, Peter Horne and Sean Lamont are also experienced options to cover the midfield.

Gordon Reid had been called up as a replacement after the first Test to replace the injured Alasdair Dickinson, but admitted the late call-up took him by surprise.

"I was having a nice day down at Ayr beach, then I have to have a word with my missus and say, 'I've got to go away'," he said.

"She was pretty angry to be honest, just because it was such short notice. She was delighted for me. It was just because I was leaving her - young love, eh!

"It is great to be here, great to be back with the boys. When the team was named at the start I was a bit disappointed, I really was, but I was happy to get a full pre-season with Glasgow. Now that I have been called out for the second week, I am pretty happy to be here.

"I brought the Scottish weather over with me. It was nice, a good surprise when you are training to have all this heat. The boys are getting used to it, they have been training in it all week.

"I have been getting used to the heat, the humidity and all that kind of thing. I think it is going to be warm in the game. I think we are going to do well."

Scotland's performance on Saturday didn't impress many despite the comfortable winning margin, but captain Greig Laidlaw was encouraged by the amount of ground covered by his team.

"A few of the boys were around the 11-kilometres mark," he said.

"Seven (km) is is a fair bit of running. Myself, Tommy (Seymour) and Hoggy (Stuart Hogg) were up there in terms of running metres, so it was a quick match and we've got the numbers to back it up.

"We coped well and came out with a victory, which was a credit to the boys when you consider the heat as well. It was a different game to the Six Nations as that is how the Japanese wanted to play.

"We matched them and if we converted a few more opportunities we would have come out with a better scoreline in our favour."
